The accused was charged with operating a motor vehicle with a blood alcohol concentration exceeding the legal limit following a traffic stop.
The defence brought a Charter application alleging that the police failed to make an approved screening device demand forthwith after forming reasonable suspicion, contrary to s. 254(2)(a) of the Criminal Code, and that the delay infringed ss. 8, 9, and 10(b) of the Charter.
The court found several unexplained delays in the investigation and concluded that the officer did not act promptly, rendering the seizure of the roadside breath sample unconstitutional and requiring exclusion of the Certificate of Analysis.
The court further held that, even absent the Charter breach, the accused’s “last drink” defence supported by corroborating testimony and expert toxicology evidence raised a reasonable doubt about the accused’s blood alcohol concentration at the time of driving.
